Hello, I’m Efe Şantay, I’m From Turkey, And My Age İs 11.
I’m Doing Trajectory Script, On Unity 5.3.2f1. And My Script Works Like That, İf Tennis Ball Game Object Was OnMouseDown, İt Does, Trajectory.SetActive(true). And İf OnMouseUp, Trajectory.SetActive(false). But My Trajectory Code Gets Error. Error Area This And Error Text: Assets/Scripts/Trajectory.cs(36,40): error CS1501: No overload for method Instantiate' takes 2’ arguments. And Here’s My Code:

using UnityEngine;

public class Trajectory : MonoBehaviour
{
	[SerializeField] int dotsNumber;
	[SerializeField] GameObject dotsParent;
	[SerializeField] GameObject dotPrefab;
	[SerializeField] float dotSpacing;
	[SerializeField] [Range (0.01f, 0.3f)] float dotMinScale;
	[SerializeField] [Range (0.3f, 1f)] float dotMaxScale;

	Transform[] dotsList;

	Vector2 pos;
	//dot pos
	float timeStamp;

    //--------------------------------
    void Start ()
	{
		//hide trajectory in the start
		Hide ();
		//prepare dots
		PrepareDots ();
	}

	void PrepareDots ()
	{
		dotsList = new Transform[dotsNumber];
		dotPrefab.transform.localScale = Vector3.one * dotMaxScale;

		float scale = dotMaxScale;
		float scaleFactor = scale / dotsNumber;

		for (int i = 0; i < dotsNumber; i++) {
			dotsList  *= Instantiate (dotPrefab, transform.position, transform.position, Quaternion.identity);*

_ dotsList .parent = dotsParent.transform;_

dotsList .localScale = Vector3.one * scale;
* if (scale > dotMinScale)*
* scale -= scaleFactor;*
* }*
* }*

* public void UpdateDots (Vector3 ballPos, Vector2 forceApplied)*
* {*
* timeStamp = dotSpacing;*
* for (int i = 0; i < dotsNumber; i++) {*
_ pos.x = (ballPos.x + forceApplied.x * timeStamp);
pos.y = (ballPos.y + forceApplied.y * timeStamp) - (Physics2D.gravity.magnitude * timeStamp * timeStamp) / 2f;_

* //you can simlify this 2 lines at the top by:*
//pos = (ballPos+forcetime)-((-Physics2D.gravitytime*time)/2f);
//
*//but make sure to turn “pos” in Ball.cs to Vector2 instead of Vector3 *

_ dotsList .position = pos;
* timeStamp += dotSpacing;
}
}*_

* public void Show ()*
* {*
* dotsParent.SetActive (true);*
* }*

* public void Hide ()*
* {*
* dotsParent.SetActive (false);*
* }*
}
See? The dotsList = Instantiate (dotPrefab, transform.position, transform.position, Quaternion.identity); İs, Gets Error. What Should I Do In The Correct Version Of This Code? Or, What Should I Choose The Corret Version Of Unity? Please, Help Me And Say The Error’s Method For Me, Ok?

Wellcome giyasefe!

The problem is that you pasted twice the transform.position value. Just get rid of one:

dotsList  *= Instantiate (dotPrefab, transform.position, Quaternion.identity);*

You can see all [Instantiate valid definitions in the Unity Documentation][1].
Good job, tho!
